HUNTSVILLE, Alabama -- Three Huntsville men have been indicted on murder charges stemming from a 2013 shooting where they are accused of hunting down a man who robbed them of a large bag of marijuana the day before.

Police investigators say witnesses said they were told the stolen pot was the property of the "Mexican Mafia" and the men would face replacing it with either cash or blood.

William Barrett Slade, Jessie McCleney Greene, Brian Andre McCrary, were indicted by the April term of the Madison County grand jury on a charge of murder, in the shooting death of 18-year-old Henry Woods.

Woods, was shot in the back multiple times on the 3400 block of Brenda Street on the morning of March 20, 2013, Huntsville Police Department investigator Michael Eichorn testified during Slade's preliminary hearing last June. Greene and McCrary waived their preliminary hearings.

During his testimony, Eichorn outlined how investigators began with the death scene of Woods in the backyard of a friend's house on Brenda Street. He said several witnesses reported seeing a gray Toyota Camry fleeing the scene.

Eichorn said police then talked to Woods' grandmother, who had raised him, and she told them two men with guns had come to their house the night before and asked that Woods come outside. She said she called police and the men left.

Eichorn said he then interviewed the man Woods was talking to at the time he was shot. The witness told the investigator that Woods said he'd robbed two men the day before at an apartment on Pulaski Pike, taking phones, wallets, a pistol and a bag of marijuana.

The witness said he and Woods were talking in his driveway when a man approached, asked Woods about buying some pot and, when Woods turned away slightly, the man began shooting. The witness said Woods ran into his house, yelling for his roommate to call police. He said someone tried the front door knob, then apparently left.

Police then confirmed a robbery report from the Pulaski Pike apartment had been called in by Greene and McCrary. Eichorn said the men said the robber had made them lie face down and he hit them with a pistol.

Eichorn testified that he received varying accounts from the men about the marijuana and whether they went to Woods' house the night before the shooting.

Eichorn testified that a relative of Greene's girlfriend said Greene called their home the day of the shooting and told them to watch TV news to see what was reported about the shooting. He also reportedly told them that the marijuana that had been stolen from them was the property of the "Mexican mafia" and they were told to collect the money or pay in blood.

Greene later agreed to talk to police, with an attorney present, Eichorn said. The interview brought Slade into the story, the investigator said. Investigators learned that several men, including Greene, Slade and McCrary went looking for Woods the night of the robbery and that Slade and possibly McCrary went to Woods' door, Eichorn said.
